The Blaser falling block rifle BL 820 became part of the series. This single shot rifle with vertical block assembly and manual cocking system had a stainless steel receiver and the barrel was set inside an octagonal carrier tube with a rail to the end of the forearm.

In 1990, after 8 successful years, it was decided that due to the extremely complicated production and therefore high price, the model would no longer be manufactured. The Blaser BL 820 is a rarity and still fetches attractive prices on the second hand market.
